i recently bought a mossberg 590a1 18.5" barrel with ghost ring sights...... i am sorry but i can not figure out how to adjust the elevation it has that disc ... how exactly does that work? i cant seem to see any movement when i turn it is it suppose to sit on top of the bumps on the disc? some one please explain this site to me......... i am use to the standard screw adjustments on normal adjustable sites..... just cant figure out how or if the sitel is moving...... thanks:banghead:

it works like a standard adjustable sight.


lift up the aperature with your hand (to get it clear of the bumps) and rotate the wheel.


the bumps are detents that keep the wheel from rotating under recoil.
